Mineral processing | Metallurgy, Crushing & Grinding
mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and ...

Depressors
DEPRESSORS are reagents, the introduction of which into the flotation process causes a decrease in the extraction of certain minerals. The use of depressors leads to the displacement of the collector from the surface of the mineral and to the creation of conditions that prevent the sorption of the collector.

Pyrite Depressant
Now there are a lot of good new reagents on a commercial scale. Aeration - The surface of the pyrite oxidizes rapidly and it floated worse. At the same time at a short aeration of the pulp extraction of copper increases. With further increase in the duration of aeration copper recovery can be reduced by 10-45%.

mineral processing summary | Britannica
mineral processing, or ore dressing, Mechanical treatment of crude ores to separate the valuable mineral s. Mineral processing was at first applied only to ores of precious metals but later came to be used to recover other metals and nonmetallic minerals. It is also used during coal preparation to enrich the value of raw coal.

Types of Mining Magnetic Separators
The iron ore grade is low, many impurities. Therefore 80% above iron minerals need magnetic separation. Manganese minerals such as psilomelane, pyrolusite, and Rhodochrosite also have weak magnetic properties and are usually recovered by magnetic separation. Ilmenite, Wolframite, Monazite, and niobium-tantalite are all weakly …
